Nice work.

I think having separate get_block (without virtual ops), get_ops [false] (with virtual operations), and get_ops [true] (just virtual operations) is deliberate and actually useful. It gives more flexibility as to what you're requesting.

However the point I would note is that there is at least one minor difference in the data obtained between get_block and get_ops. For vote transactions you get the signature with get_block. This is not the case for get_ops.
